What is Svelte?
Svelte is a free, open source front-end compiler, that is used to build graphical interfaces for web applications. It was created in November 2016 by Rich Harris. Svelte's predecessor is a project called Ractive.js. Currently, Svelte is being rewritten to TypeScript.
The difference between Svelte and React
Svelte state management
Svelte has several ways of dealing with state management. We can use the Context API or we can use Svelte stores. Svelte has two types of stores for managing state: writable and readable. Writable Stores are objects that store values or attributes that can be accessed by different components. We use Writable Stores when we want to store values with the possibility of changing them later. Readable stores, on the other hand, are also used to store different values, but they cannot be updated.
